“The contact owns a 2016 Buick Cascada. The contact stated that the rear windshield glass had begun to separate from the convertible top headliner. The contact attempted to repair the failure by using epoxy glue, but the failure returned over time. The contact took the vehicle to a dealer where she was provided a quote to replace the top. Upon investigation, the contact discovered a service bulletin Manufacturer Communication Number: 17NA216 which she linked to the failure. The manufacturer was notified of the failure but provided no assistance. The vehicle was not repaired. …”

“The rear window on the Cascada is known to separate from the convertible top material, likely due to an insufficient amount of primer used during the assembly process, which creates stress points allowing the material to separate from the glass. Once this bond has started to fail, it is eventually going to lead to the glass completely falling off the car. It is likely that the glass separating could render the rear defrost inoperable, too, decreasing visibility. NHTSA bulletin 17-NA-216 describes this problem; why was no recall ever issued?”
